Given my husband's previous and current employment, the silicone rings were really our only option. We bought these as a replacement for the original set we had purchased from another manufacuturer. We had had them for a couple years and given how hard we are on them, it was no surprise that they were starting to need replaced.
I decided to give this brand a shot because it gave us more color options in the set. Color options that we would actually wear, so I didn't feel I was wasting money on things we would never wear. So far, these have been amazing. They are even more comfortable than our original ones and, even though the outer portion is shaped differently, there isn't really any adjustment period that you typically deal with when switching rings.
I do recommend that you order up a size. My husband typically wears a 10 but after looking at these, I decided to order the 11. It was the right choice. They aren't loose at all and it is clear that the 10 would have been too small for him.
